Narrated by Oscar-winning actor Jeremy Irons, "Life on Fire" series offers a close up look at volcanoes, providing viewers with a never seen before look at their effect on the environment around them.

Each episode of "Life on Fire" paints survival stories around different volcanoes. From the dark abyss to pristine snow-capped peaks, spectacular scenery provides the backdrop for the extraordinary animals and plants that have learned to juggle with fire. Each time a volcano erupts, animals have a choice: face the consequences or flee. And because these animals are adapted to living with fire, often they run straight into another volcano and another explosion- out of the frying pan into the fire. Fragile and engaging, these creatures teach us lessons in survival in a world as fascinating as it is dangerous. (Source: PBS)

The series finale travels to the Tonga archipelago in the South Pacific, where tectonic movements can construct or swallow islands. Included: how the sooty tern and Alvin shrimp have adapted to life around such ephemeral lands.
